ABSTRACT

Background and study aims Z-POEM is now an established therapy for symptomatic Zenker's diverticulum (ZD). Short-term follow-up of up to 1-year post Z-POEM suggests excellent efficacy and safety; however, long-term outcomes are not known. Thus, we sought to report on longer-term outcomes (≥ 2 years) following Z-POEM for treatment of ZD. Patients and methods This was an International multicenter retrospective study at eight institutions across North America, Europe, and Asia over a 5-year period (from December 3, 2015 to March 13, 2020) of patients who underwent Z-POEM for management of ZD with a minimum 2-year follow-up. The primary outcome was clinical success, defined as improvement in dysphagia score to ≤ 1 without need for further procedures during the first 6 months. Secondary outcomes included rate of recurrence in patients initially meeting clinical success, rate of reintervention, and adverse events (AEs). Results A total of 89 patients (male 57.3 %, mean age 71 ±â€Š12 years) underwent Z-POEM for treatment of ZD (mean diverticulum size was 3.4 ±â€Š1.3 cm). Technical success was achieved in 97.8 % of patients (n = 87) with a mean procedure time of 43.8 ±â€Š19.2 minutes. The median post-procedure hospital stay was 1 day. There were eight AEs (9 %) (3 mild, 5 moderate). Overall, clinical success was achieved in 84 patients (94 %). Mean dysphagia, regurgitation, and respiratory scores all improved dramatically from 2.1 ±â€Š0.8, 2.8 ±â€Š1.3, and 1.8 ±â€Š1.6 pre-procedure to 0.13 ±â€Š0.5, 0.11 ±â€Š0.5, and 0.05 ±â€Š0.4, respectively, post-procedure at most recent follow-up (all P  < 0.0001). Recurrence occurred in six patients (6.7 %) during a mean length of follow-up of 37 months (range 24 to 63 months). Conclusions Z-POEM is a highly safe and effective treatment for Zenker's diverticulum with durable treatment effect to at least 2 years.

ABSTRACT

The concept of third space endoscopy first described in 2007, was adapted and performed in humans in 2010 by Inoue et al. in a group of patients with esophageal achalasia (EA). Since then, esophageal endoscopic myotomy (E-POEM), has been performed in more than 10,000 patients worldwide up to now. Safety and efficacy have been confirmed at early, mid and long-term evaluations, in different gastrointestinal diseases including achalasia, refractory gastroparesis, and other esophageal motility disorders (EMD). Nowadays, this treatment has shown to be not only an excellent option, but also with its excellent outcomes, the first option in certain clinical scenarios such as type III achalasia. Thus, the minimal invasive nature of POEM gives us multiple advantages compared with the classical treatments that includes pneumatic dilation (PD) and laparoscopic Heller myotomy (LHM), including not only clinical aspects but also economical. High resolution manometry (HRM) has substantially redefined the actual approach of esophageal motility disorders with the major changes in instrumental use, diagnostic algorithms, and therapeutics. The previous Chicago's classification V 3.0 clearly improved our knowledge about pathophysiology of spastic esophageal motor disorders, however, with its recent update (Chicago V 4.0), multiple changes in diagnosis and treatment are expected. In the present article, we aimed to review and analyze the most important aspects about the results of E-POEM in the management of EMD according to the view of the new Chicago's classification V 4.0.

ABSTRACT

BACKGROUND: Zenker's diverticulum peroral endoscopic myotomy (zPOEM) is a minimally invasive treatment strategy for Zenker's diverticulum, with excellent results for management of small-to-moderate Zenker's diverticulum. We evaluated its use in the management of large Zenker's diverticulum. METHODS: This was a retrospective multicenter cohort study across 11 international centers including adult patients with large Zenker's diverticulum ≥ 40 mm treated by zPOEM between March 2017 and March 2022. The primary outcome was clinical success (dysphagia score ≤ 1 without need for further intervention). Secondary outcomes included technical success (complete myotomy as intended), adverse events (AEs), and rate of recurrence. RESULTS: 83 patients (male 62.7 %, mean age 72.6 [SD 11.5] years) underwent zPOEM for treatment of large Zenker's diverticulum (median size 50 mm, interquartile range [IQR] 41-55 mm, range 40-80 mm). The zPOEM procedure was technically successful in 82 patients (98.8 %), with a mean procedure time of 48.7 (SD 23.2) minutes. Clinical success was achieved in 71 patients (85.5 %). Median (IQR) symptom scores improved significantly from baseline for dysphagia (2 2 3 vs. 0 [0-2]; P < 0.001), regurgitation (3 2 3 4 vs. 0 [0-0]; P < 0.001), and respiratory symptoms (2 [0-3] vs. 0 [0-0]; P < 0.001). Among patients achieving clinical success, only one recurrence (1.4 %) was recorded during a median follow-up of 12.2 months (IQR 3-28). Post-procedure AEs, all mild to moderate, occurred in four patients (4.8 %). CONCLUSION: This study demonstrated safe and effective use of zPOEM in the management of large Zenker's diverticulum.

ABSTRACT

INTRODUCTION: retention is the most common adverse event of the small bowel capsule endoscopy procedure. Patency capsule (Medtronic, Dublin, Ireland) and magnetic resonance enterography are two diagnostic methods that can prevent small bowel capsule endoscopy retention. The aim of this study was to evaluate the predictive value of these two diagnostic methods. MATERIAL AND METHODS: a prospective, comparative and observational study was performed in patients with established Crohn's disease. All patients had undergone magnetic resonance enterography and patency capsule procedures. If the patency capsule was not retained, the patient underwent a small bowel capsule endoscopy; otherwise, double balloon enteroscopy was performed to locate the stenosis. Magnetic resonance enterography predictive criteria for retention were analyzed in all cases. Sensitivity, specificity, positive predictive value and negative predictive value of the patency capsule and magnetic resonance enterography compared to small bowel capsule endoscopy or double balloon enteroscopy were calculated. RESULTS: forty patients were included (24 female, 55 ± 13 years old). Retention criteria with capsule endoscopy or double balloon enteroscopy were found in six patients, agreeing in five cases with patency capsule and in three cases with magnetic resonance enterography. Sensitivity, specificity, positive predictive value, negative predictive value and Kappa coefficient for predicting retention with the patency capsule were 83 %, 100 %, 100 % and 97 %, respectively, and 50 %, 91 %, 50 % and 91 %, respectively, with magnetic resonance enterography. CONCLUSIONS: patency capsule has a higher sensitivity and positive predictive value than magnetic resonance enterography for preventing small bowel capsule endoscopy retention in Crohn's disease patients.

ABSTRACT

Introduction: The diagnostic yield (DY) of small-bowel capsule endoscopy (SBCE) varies considerably according to its indication. Some strategies have been used to increase DY with varying results. The intention of this study was to identify whether evaluation of the SBCE recordings by a second reviewer can increase DY and change patient management. Methods: One hundred SBCEs with different indications, already read by an endoscopist were read by a second blinded endoscopist. When the results of the 2 readings were different, the images were discussed by the endoscopists; if no consensus was reached, they took the opinion of a third endoscopist into account. All the participating endoscopists had experience in reading SBCEs (i.e., >50 per year). The SBCE findings were divided into positive (vascular lesions, ulcers, and tumors), equivocal (erosions or red spots), and negative. The interobserver agreement and the increase in DY were assessed as well as the percentage of false-negatives (FNs) in the first evaluation. Results: The indications for SBCE were small-bowel bleeding (SBB) in 48 cases, Crohn's disease (CD) in 30, and other causes (iron-deficiency anemia, small-bowel tumors, and diarrhea) in 22. There was substantial interobserver agreement between evaluations (κ = 0.79). The findings in the first evaluation were positive in 60%, equivocal in 20% and, negative in 20%. In the second evaluation, 66% were positive, 18% were equivocal, and 16% were negative. The increase in DY with the second reading was 6% (p = 0.380), i.e., 6.3% for SBB, 4.4% for CD and 9.2% for other indications, resulting in a change in management of 4% of the patients. FNs in the first SBCE reading were found in 4% of the SBCEs. Discussion: A second evaluation of the SBCE recordings identified significant pathology that the first evaluation had missed, resulting in a nonsignificant 6% increase in DY and a change in the management of 4% of the patients.


Introdução: O rendimento diagnóstico (DY) da enteroscopia por cápsula (SBCE) varia consideravelmente de acordo com as suas indicações. Foram estudadas algumas estratégias para melhorar o DY, com resultados variados. O objetivo deste estudo é avaliar se uma segunda leitura de registos de enteroscopia por cápsula por um segundo endoscopista pode melhorar o DY e alterar o manejo dos doentes. Métodos: 100 SBCE realizadas por indicações variadas, previamente avaliadas por um endoscopista, foram reavaliadas por um segundo endoscopista cego para a primeira leitura. Na presença de resultados discordantes nas 2 leituras, as imagens foram discutidas pelos 2 endoscopistas, e por um terceiro na ausência de consenso entre os 2 primeiros. Todos os endoscopistas são experientes na leitura de SBCE (>50 SBCE/ano). Os achados foram categorizados em positivos (lesões vasculares, úlceras e tumores), equívocos (erosões e pontos vermelhos) e negativos. Foi avaliada a concordância inter-observador e o aumento do DY, bem como a percentagem de falsos negativos da primeira avaliação. Resultados: As indicações para SBCE foram hemorragia do intestino delgado (SBB) em 48 casos, doença de Crohn (CD) em 30 e outras causas (anemia por défice de ferro, pesquisa de tumores do intestino delgado e diarreia) em 22. A concordância inter-observador foi substancial (k = 0.79). Os achados da primeira avaliação foram positivos em 60%, equívocos em 20% e negativos em 20%, enquanto na segunda avaliação foram positivos em 66%, equívocos em 18% e negativos em 16%. O aumento de DY foi de 6% com a segunda leitura (p = 0.38), sendo 6.3% para SBB, 4.4% para CD e 9.2% para outras indicações, resultando numa alteração no manejo de 4% dos doentes. Foram identificados falsos negativos na primeira avaliação em 4% das SBCE. Conclusão: A segunda avaliação dos registos de SBCE identificou patologia significativa previamente não identificada, resultando num aumento não significativo de 6% do DY e numa alteração no manejo de 4% dos doentes.

ABSTRACT

BACKGROUND AND AIMS: Gastric peroral endoscopic myotomy (G-POEM) is used for refractory gastroparesis (RG) with good early-term but variable mid- and long-term outcomes. Limited data exist about candidates and long-term clinical and predictive factors. Our aim was to evaluate the 4-year follow-up efficacy and predictive factors in patients with RG. METHODS: Confirmed RG patients were included and evaluated between April 2017 and December 2021. Gastroparesis Cardinal Symptom Index (GCSI) score, retention percentage at 4 hours (RP4H), mean half-emptying time (MHET), and the 36-item short-form survey (SF-36) were performed at 1, 6, 12, 18, 24, 30, 36, 42, and 48 months. RESULTS: After G-POEM, 374 patients with RG were included: 141 patients (37.7%) had diabetic gastroparesis (DG), 115 (30.7%) had idiopathic gastroparesis (IG), 102 (27.3%) had postsurgical gastroparesis (PSG), and 16 (4.3%) had other etiologies. After the 48-month evaluation, 102 patients completed follow-up (DG, 58; IG, 22; PSG, 18; other, 4). Before G-POEM, GCSI score, RP4H, and MHET were 3.84 ± .53, 44% (interquartile range [IQR], 11-68), and 246 minutes (IQR, 150-368), respectively, and after the 48-month evaluation improved to 2.1 ± .70 (P < .001), 15.5% (IQR, 0-36; P = .021), and 135 minutes (IQR, 67-290; P = .045), respectively. At the 48-month evaluation, clinical success was 77.5%. DG showed the best outcomes (DG vs IG vs PSG vs other: 86.5% vs 72.5% [P = .001] vs 72.1% [P = .003] vs 68.8% [P < .001]). Long-term success predictors were DG (odds ratio [OR], 5.113; 95% confidence interval [CI], 1.643-5.981; P = .035), early diagnosis (OR, 2.455; 95% CI, 1.129-3.522; P = .042), nausea/vomiting (OR, 3.541; 95% CI, 1.881-5.511; P = .012), GCSI score at 6 months (1.5-2) (OR, 3.612; 95% CI, 2.122-5.317; P = .022), and RP4H <10% at 6 months (OR, 2.188; 95% CI, 1.435-4.233; P = .039). CONCLUSIONS: G-POEM is an effective 4-year treatment in patients with RG, especially in DG, establishing a potential first-line therapy in these patients. However, randomized controlled clinical trials are needed to confirm these results. (Clinical trial registration number: NTC03126513.).

ABSTRACT

BACKGROUND: Cricopharyngeal bars (CPBs) are a unique etiology of oropharyngeal dysphagia. Symptomatic patients are managed with endoscopic dilation or surgical myotomy. Cricopharyngeal peroral endoscopic myotomy (CP-POEM) is an emerging technique for the management of dysphagia due to CPBs. This study evaluated technical success, clinical success, adverse events, and long-term recurrence following CP-POEM. METHODS: Consecutive patients who underwent POEM for management of CPBs between May 2015 and December 2020 at four tertiary care centers were included. Primary outcome was clinical success (defined as improvement of dysphagia score to ≤ 1). Secondary outcomes were technical success, rate and severity of adverse events, procedure duration, and symptom recurrence. RESULTS: 27 patients (mean age 69 years; 10 female) underwent CP-POEM during the study period. The most common presenting symptoms at the time of index procedure were dysphagia (26; 96.3 %) and regurgitation (20; 74.1 %). Clinical and technical success were achieved in all patients. Mild/moderate adverse events occurred in two patients (7.4 %). CP-POEM significantly reduced the median dysphagia score. CONCLUSIONS: CP-POEM was a safe and effective treatment for symptomatic CPBs. Although symptom recurrence was low, long-term outcome data are needed. CP-POEM should be considered as a management option for symptomatic CPBs at centers with POEM expertise.

ABSTRACT

BACKGROUND: Treatment of Zenker's diverticulum has evolved from open surgery to endoscopic techniques, including flexible and rigid endoscopic septotomy, and more recently, peroral endoscopic myotomy (Z-POEM). This study compared the effectiveness of flexible and rigid endoscopic septotomy with that of Z-POEM. METHODS: Consecutive patients who underwent endoscopic septotomy (flexible/rigid) or Z-POEM for Zenker's diverticulum between 1/2016 and 9/2019 were included. Primary outcomes were clinical success (decrease in Dakkak and Bennett dysphagia score to ≤ 1), clinical failure, and clinical recurrence. Secondary outcomes included technical success and rate/severity of adverse events. RESULTS: 245 patients (110 females, mean age 72.63 years, standard deviation [SD] 12.37 years) from 12 centers were included. Z-POEM was the most common management modality (n = 119), followed by flexible (n = 86) and rigid (n = 40) endoscopic septotomy. Clinical success was 92.7 % for Z-POEM, 89.2 % for rigid septotomy, and 86.7 % for flexible septotomy (P = 0.26). Symptoms recurred in 24 patients (15 Z-POEM during a mean follow-up of 282.04 [SD 300.48] days, 6 flexible, 3 rigid [P = 0.47]). Adverse events occurred in 30.0 % rigid septotomy patients, 16.8 % Z-POEM patients, and 2.3 % flexible septotomy patients (P < 0.05). CONCLUSIONS: There was no difference in outcomes between the three treatment approaches for symptomatic Zenker's diverticulum. Rigid endoscopic septotomy was associated with the highest rate of complications, while flexible endoscopic septotomy appeared to be the safest. Recurrence following Z-POEM was similar to flexible and rigid endoscopic septotomy. Prospective studies with long-term follow-up are required.

ABSTRACT

Backgrounds and study aims Treatment of octogenarian patients with achalasia with conventional treatments is effective but with compromised safety. Biodegradable stents (BS) are promising. We aimed to evaluate their safety, efficacy and clinical outcomes at early, mid and long-term in this population. Patients and methods Naïve or previously-treated achalasic octogenarian patients underwent to BS placement (BSP) between December, 2010 and November, 2011, and were followed-up for 9-years. A strict follow-up was performed. Results Thirty-two patients were included, (17 men [53.1 %]; median age 82 years [78-92]). BSP was performed in all patients. At 9y, 18/32 (56.2 %) completed protocol. Mean BSP time was 37.5±12.1 min and 34.4 % presented thoracic pain. At 1 m, six BS were migrated (18.7 %), requiring a second BSP fixed with hemoclips. At 3 m, twenty-three (72.8 %) completed degradation process. At 6 m, eighteen (56.2 %) presented clinical dysphagia, of whom 5/32 (15.6 %) presented stenotic-tissue hyperplasia, responding to balloon dilation in all cases. Pre-BSP Eckardt, Timed barium esophagram and integrated relaxation pressure improved post-BSP 6 m values (9 vs 2, p = 0.001; < 50 % = 93.8 % vs > 80 % = 81.5 %, p = 0.003 and 18.8 ±â€Š3.2 vs 11.1 ±â€Š2.6 mmHg, p = 0.001, respectively), and there were no significant changes up to 9y post-BSP. Esophagitis grade A or B was presented between 4.7 % to 11.2 % and controlled with PPI. After 9 years we had clinical success rates of 94.4 %, 72 %, and 65.4 % for time point evaluation, per protocol and intention to treat analysis, respectively. Conclusions BSP represents a feasible alternative option in octogenarian patients with achalasia who are high risk with other treatments, presenting acceptable early, mid-, and long-term outcomes.

ABSTRACT

BACKGROUND AND AIMS: Digestive endoscopy is considered a high-risk procedure for COVID-19. Recommendations have been made for its practice during the pandemic. This study was conducted to determine adherence to recommendations for endoscopy practice during the COVID-19 pandemic in Latin America (LA). METHODS: A survey was conducted of endoscopists from LA consisting of 43 questions for the evaluation of four items: general and sociodemographic features, and preprocedure, intraprocedure and postprocedure aspects. RESULTS: A response was obtained from 338 endoscopists (response rate 34.5%) across 15 countries in LA. In preprocedure aspects (hand washing, use of face masks for patients, respiratory triage area, training for the placement/removal of personal protective equipment (PPE) and availability of specific area for the placement/removal of PPE), there was adherence in <75%. Regarding postprocedure aspects, 77% (261/338) had reused PPE, mainly the N95 respirator or higher, and this was with a standardised decontamination procedure only in 32% (108/338) of the time. Postprocedure room decontamination was carried out by 47% on >75% of occasions. In relationship to intraprocedure aspects (knowledge of risk and type of endoscopic procedures, use of PPE, airway management in patients and infrastructure), there was adherence in >75% for all the parameters and 78% of endoscopists only performed emergencies or time-sensitive procedures. CONCLUSIONS: Adherence to the recommendations for endoscopy practice during the COVID-19 pandemic is adequate in the intraprocedure aspect. However, it is deficient in the preprocedure and postprocedure aspects.

ABSTRACT

INTRODUCTION: Capsule endoscopy (CE) is the first-line tool for diagnosis of small bowel bleeding. There are some studies that have compared different types of CE. OMOM CE is one of the newest in the market and has not been compared with other types of CE. The objective of this study was to compare the diagnostic yield of the Pillcam SB3 and OMOM CE in small bowel bleeding. MATERIALS AND METHODS: This is a prospective, comparative, randomized, and blinded study. Patients with suspected small bowel bleeding were included. All the patients were given both types of CE in random order. Diagnostic yield and functionality between the 2 types of CE were analyzed. RESULTS: We included 44 patients, 54.5% were female with a median age of 63.5 years. Battery time was significantly longer with SB3 (816.5 vs. 700.5 min, p < 0.001), and the download time was shorter with OMOM (33 vs. 132 min, p < 0.001). Both CEs presented 1 failure. The cause of the bleeding was identified in 39 SB3 (88.6%) and in 34 OMOM CE (77.3%) (p = 0.256). P2 lesions were observed in 32 SB3 (72.7%) and in 29 OMOM CE (65.9%) (p = 0.784). The agreement between both CEs for P2 lesions was moderate (κ = 0.628). CONCLUSIONS: Pillcam SB3 and OMOM devices are safe procedures and have a similar diagnostic yield. Significant differences were observed in the battery life and download time with both CEs.

ABSTRACT

BACKGROUND: Third-space endoscopy is a novel, safe, and effective method for treating different gastrointestinal conditions. However, several failed endoscopic procedures are attributed to incomplete myotomy. Lighting devices are used to prevent organic injuries. We aimed to investigate the feasibility of using a hand-made LED-probe (LP) in third-space procedures. METHODS: This prospective study was conducted in a tertiary-care center in Mexico between December 2016 and January 2019. We included peroral endoscopic myotomy (POEM) and gastric peroral endoscopic myotomy(G-POEM) procedures. Pseudoachalasia, peptic ulcer, normal gastric emptying scintigraphy (GES) and prepyloric tumors were excluded. LP was used to guide or confirm procedures. Clinical and procedural characteristics were recorded and analyzed. RESULTS: Seventy third-space procedures were included (42POEM,28G-POEM), with an average patient age of 46.7 ± 14.3 and 43.7 ± 10.1 years, respectively. For the POEM and G-POEM groups, respectively, 18/42(42.9%) and 13/28(46.7%) patients were males; median procedure times were 50 (interquartile range [IQR]: 38-71) and 60(IQR: 48-77) min, median LP placement times were 5(IQR: 4-6) and 6(IQR: 5-7) min, mild adverse events occurred in 4(9.4%) and 4(14.2%) of cases, and clinical success at 6 months occurred in 100 and 85.7% of cases. Integrated relaxation pressure (IRP) improved from 27.3 ± 10.8 to 9.5 ± 4.1 mmHg (p < 0.001); retention percentage at 4 h also improved. LP was successfully placed and adequate myotomy confirmed including 14.2 and 17.8% of POEM and G-POEM difficult patients. CONCLUSIONS: Using an LP is promising and allows guiding during third-space procedures either for submucosal tunnel creation or myotomy confirmation, with excellent safety and efficacy in clinical practice.

ABSTRACT

BACKGROUND: new alternatives for entry site closure (ESC) in per-oral endoscopy myotomy (POEM) and gastric peroral endoscopy myotomy (G-POEM) have appeared. OBJECTIVE: to compare the over-the-scope-clip (OTSC®) and conventional clips (CC) for ESC in POEM and G-POEM. MATERIAL AND METHODS: a retrospective review of a prospective POEM and G-POEM database was performed between January 2015 and August 2019. A description was made of outcomes, using either OTSC® or CC for submucosal tunnel closure. RESULTS: forty-six POEM and 26 G-POEM were included in the study (23/13 per group [CC/OTSC®]). There were no clinical or procedure differences. ESC was performed with 1 OTSC® vs 5 CC and 1 vs 6 (p = 0.01) for POEM and G-POEM, respectively. Adverse events associated with clips were 21.7% vs 13% (p = 0.01) and 7.7% vs 0% (p = 0.02) for CC and OTSC® in POEM and G-POEM, respectively. CONCLUSION: OTSC® represents a safe and effective alternative for entry site closure in POEM and G-POEM cases. Further studies are needed to recommend OTSC® as the first option for submucosal tunnel closure in these procedures

ABSTRACT

BACKGROUNDS AND AIMS: New mucosal resective and ablative endoscopic procedures based on gastric cardiac remodeling to prevent reflux have appeared. We aimed to evaluate the feasibility of a new ablative technique named antireflux ablation therapy (ARAT) for control of GERD in patients without hiatal hernia. METHODS: Patients with proton pump inhibitor (PPI)-refractory GERD without hiatal hernia underwent ARAT between January 2016 and October 2019. Gastroesophageal Reflux Disease-Health-Related Quality of Life (GERD-HRQL), upper endoscopy, 24-hour pH monitoring, and PPI use were documented at 3, 6, 12, 24, and 36 months after ARAT. RESULTS: One hundred eight patients were included (61 men [56.5%]; median age, 36.5 years; range, 18-78 years). ARAT was performed on all patients. At the 36-month evaluation, 84 patients had completed the protocol. Median ARAT time was 35.5 minutes (range, 22-51 minutes), and median circumference ablation was 300° (range, 270°-320°). No major adverse events occurred, and 14 of 108 patients (12.9%) presented with stenosis that was responsive to balloon dilation (<5 sessions). At the 3-month evaluation, the acid exposure time (AET), DeMeester score, and GERD-HRQL score had decreased from 18.8% to 2.8% (P = .001), 42.5 to 9.1 (P = .001), and 36.5 to 10 (P = .02), respectively, and these values were maintained up to 36 months. Success (AET <4%) was achieved in 89% and 72.2% at 3 and 36 months, respectively. Related factors at 36 months were as follows: pre-ARAT Hill type II (odds ratio [OR], 3.212; 95% confidence interval [CI], 1.431-5.951; P = .033), post-ARAT 3-month Hill type I (OR, 4.101; 95% CI, 1.812-9.121; P = .042), and AET <4% at 3 months (OR, 5.512; 95% CI, 1.451-7.621; P = .021). CONCLUSIONS: ARAT is a feasible, safe, and effective therapy for early and mid-term treatment of GERD in patients without a sliding hiatal hernia. However, longer follow-up evaluations and randomized comparative studies are needed to clarify its real role. (Clinical trial registration number: NCT03548298.).

ABSTRACT

INTRODUCTION: the aim of this study was to determine the risk factors for rebleeding following device-assisted enteroscopy therapy of small bowel vascular lesions. METHODS: this is a systematic review and meta-analysis. A literature search was performed from January 2003 to October 2019. All studies reporting on at least one risk factor for bleeding recurrence after endoscopic therapy of small bowel vascular lesions were included. A meta-analysis of those risk factors reported in at least three studies was performed to assess their association with rebleeding. The OR and 95 % CI were used for binary outcome data. Heterogeneity analysis was performed using the Tau and I2 index. If I2 > 20 %, potential sources of heterogeneity were identified by sensitivity analyses and a random-effect model was used. RESULTS: the search identified a total of 572 articles and 35 full-text records were assessed for eligibility after screening. Finally, eight studies that included 548 patients were selected. The overall median rebleeding rate was 38.5 % (range: 10.9-53.3 %) with a median follow-up of 24.5 months. Female sex (OR: 1.96, 95 % CI: 1.14-3.37, p = 0.01, I2 = 0 %), Osler-Weber syndrome (OR: 4.35, 95 % CI: 1.22-15.45, p = 0.02, I2 = 0 %) and cardiac disease (OR: 1.89, 95 % CI: 1.12-2.97, p = 0.005, I2: 0 %) were associated with rebleeding. According to the sensitivity analysis, overt bleeding (OR: 2.13, 95 % CI: 1.22-3.70, p = 0.007, I2 = 0 %), multiple lesions (OR: 4.57, 95 % CI: 2.04-10.22, p < 0.001, I2 = 0 %) and liver cirrhosis (OR: 2.61, 95 % CI: 1.11-6.13, p = 0.03, I2 = 0 %) were also predictors for rebleeding. CONCLUSIONS: patient characteristics and comorbidities should be considered for follow-up patient management after effective device-assisted endoscopic therapy, as they can predict rebleeding

ABSTRACT

INTRODUCCIÓN: la insuflación de dióxido de carbono (CO2) durante la enteroscopia reduce el tiempo del procedimiento y los síntomas posteriores al mismo e incrementa la profundidad de inserción comparado con aire ambiente. En colonoscopia, la técnica de intercambio de agua (IA) se asocia a menor dolor en comparación con la insuflación de CO2. La técnica IA no está bien estudiada en enteroscopia. El objetivo de este estudio es comparar la seguridad y eficacia de la enteroscopia con IA y la enteroscopia con CO2. MÉTODOS: estudio prospectivo, comparativo y observacional, que incluyó enteroscopias de doble balón (EDB) que fueron aleatorizadas en dos grupos: el primero con IA y el segundo con insuflación de CO2. Los datos recopilados se evaluaron mediante análisis univariado y una regresión logística múltiple (variables con p ≤ 0.10 en análisis univariado). RESULTADOS: se incluyeron 46 EDB (23 por brazo; mediana de edad 63,5 años, 37% mujeres). No hubo diferencias estadísticas en la vía de acceso, los hallazgos, la terapéutica y las complicaciones entre grupos. Cuatro pacientes (20%) en el grupo de CO2 tuvieron eventos adversos (distensión abdominal y dolor) y uno en el grupo IA (náuseas) sin diferencia estadística. La mediana de profundidad de inserción fue mayor en el grupo de CO2 (260 cm vs. 160 cm; p = 0,048). La regresión logística múltiple mostró una diferencia estadística en la profundidad de inserción utilizando insuflación de CO2 (OR 1,009, 1,001-1,017; p = 0,034). CONCLUSIONES: las EDB con técnica de insuflación de CO2 y con IA son seguras con una mayor profundidad de inserción con CO2

ABSTRACT

INTRODUCCIÓN Y OBJETIVO: estudios han evaluado la concordancia entre la cápsula endoscópica y la enteroscopia doble-balón con resultados diversos. El objetivo de este estudio es identificar factores que predicen la visualización de las lesiones en el intestino delgado por enteroscopia doble-balón después de una cápsula endoscópica positiva. MÉTODOS: estudio retrospectivo, observacional y comparativo que evaluó a pacientes con enteroscopia doble balón después de un cápsula endoscópica positiva entre enero de 2017 y agosto de 2019. Los datos estudiados fueron demográficos, indicaciones, comorbilidades y resultados de cápsula endoscópica y enteroscopia doble-balón. Se evaluaron mediante una regresión logística múltiple. RESULTADOS: se incluyeron 91 pacientes (edad 58 ± 16,5 años, 53 mujeres). Sesenta y dos enteroscopia doble-balón (68,1 %) encontraron las mismas lesiones que la cápsula endoscópica. Los factores predictivos para enteroscopia doble-balón positiva fueron lesiones múltiples (OR 8,10, 1,50-43,78; p = 0,015) y < 15 días ambos estudios (OR 5,31, 1,19-23,66; p = 0,029). En el subgrupo de pacientes con hemorragia de intestino delgado (70 pacientes), 46 enteroscopia doble-balón (65,7 %) coincidieron con la cápsula endoscópica. Los factores predictivos en este grupo fueron lesiones múltiples (OR 10,42, 1,37-79,30; p = 0,024), < 15 días entre ambos estudios (OR 13,51, 1,78-102,22; p = 0,012), > 60 años (OR 7,45, 1,51-36,75; p = 0,014) y úlceras (OR 4,67, 1,08-20,22; p = 0,039). CONCLUSIONES: los factores predictivos para enteroscopia doble-balón positiva después de cápsula endoscópica positiva son lesiones múltiples y < 15 días entre ambos procedimientos. En pacientes con hemorragia de intestino delgado, edad mayor a 60 años y presencia de úlceras también son
